It should also be kept in mind that Ukraine
utilized road basing and dirt strips to preserve their aircraft while on the ground. Most groundside losses had in fact happened
during opening days of the war before Ukrainians had had the time to disperse their aircraft to road bases and backup air fields – Ukraine had lost six of its 30 MiG-29s in a single attack, and almost no losses on the ground had happened after 27 February. It is entirely likely that Western air forces would have suffered far more extensive losses on the ground. In fact, Ukrainian usage of Russian aircraft was a major advantage precisely because of their ability to use rough fields and half-fallen-apart airstrips, and their STOL capability giving them ability to operate from highways as well.
Currently, Ukrainian aircraft and crews operate from
ad-hoc secret bases established after the war has begun. These can be old dispersal air fields as well as aircraft shelters constructed near highways and other roads, with fighter jets
taking off those same roads. This is the only way for them to survive the threat of Russian missile strikes that had been so devastating in the opening days of the war. And Ukraine was aware of this problem. Ukrainian Air Force had been training in operating from dispersed road bases since at least the 2014. Crimean War.
